Subject [jira] [Commented] (GIRAPH-45) Improve the way to keep outgoing messages
Date Tue, 15 Nov 2011 21:17:51 GMT

Jake Mannix commented on GIRAPH-45:
-----------------------------------

@Jakob

My comment about avoiding disk *and* having too-large message-sets is that in this combined
case, your only option is to break BSP somehow, if you can't properly use Combiners.

I think spilling to disk on the target side is a good idea, as it allows Combiners to be attempted
both on sender-side, and reciever, and if you *still* have too much to hold in memory, you
spill.

> As discussed in GIRAPH-12(http://goo.gl/CE32U), I think that there is a potential problem
to cause out of memory when the rate of message generation is higher than the rate of message
flush (or network bandwidth).
> To overcome this problem, we need more eager strategy for message flushing or some approach
to spill messages into disk.
